The present invention relates to an anhydrous dyeing composition whichis liquid at 20° C. comprising one or more oil liquid at 20° C., one ormore direct dyes, at least one anionic surfactant and at least onenonionic surfactant for achieving intensive homogeneous colors on hair.

Hair coloring has been known for many decades. Chemically hair colouringmay be divided into two categories. One of them is the oxidative dyeingwhich bleaches hair besides coloring and the other is the dyeing withoutchanging the basic hair color with the aid of the direct dyes. Coloringwith direct dyes adds color onto the basic hair color but notnecessarily removes color as for achieving dyeing use of an oxidizingagent is not required. Achieving intensive and homogeneous color is theunchanged need independent form the technology used for dyeing hair.There have been attempts made to achieve intensive, homogeneous and longlasting colors with the use of direct dyes but there is still need ofadditional superior technologies which delivers exceptional benefits tothe consumers.

The present invention starts from the problems of need of achievingintensive, homogeneous and long lasting colors with the use of directdyes either in the presence or in the absence of an oxidizing agent andespecially for the hair which comprises various parts with variousdegree of damage because of the chemical treatments and/or environmentalinfluences and aims at providing an oxidative hair dyeing compositionwhich delivers homogeneous and long lasting intensive colors especiallyto a hair comprising parts with different degree of damage form previouschemical and/or environmental effects.
